DETAILED DESCRIPTION OF THE INVENTION

With reference to FIGS. 1A, 1B and 2, a foldable cardboard template 10 in accordance with the present invention has an outer panel 20, four binding strips 30 and an interlayer board 40. The outer panel 20 is rectangular and has two transverse sides 22, two longitudinal sides 23 and a center fold line 21. The center fold line 21 is centrally formed on the outer panel 20 and is parallel with the transverse sides 22. The binding strips 30 are trapezoidal. Two of the binding strips 30 are respectively formed on and protrude from the transverse sides of the outer panel 20. The other two binding strips 30 are respectively formed on and protrude from one of the longitudinal sides of the outer panel 20, and are symmetrical with respect to the center fold line 21. The interlayer board 40 is formed on and transversely protrudes from the longitudinal side of the outer panel 20 having no binding strip formed thereon, and has multiple interlayers, multiple partition lines 41 and multiple card slits 401. The interlayer board 40 is divided into the interlayers. As indicated by a portion highlighted by a circle in FIG. 1B, the interlayer board 40 is ladder-like and the interlayers of the interlayer board 40 are transversely connected with each other. Each interlayer has a longitudinal side and the longitudinal sides of the interlayers gradually decrease in length in a direction away from the outer panel 20. The center fold line 21 of the outer panel 20 transversely extends across the interlayer board 40 to bisect the interlayer board 40. With reference to FIGS. 3 and 4, the partition lines 41 respectively coincide with the longitudinal sides of the interlayers and are formed on the interlayer board 40 in parallel to the longitudinal sides of the outer panel 20 for the interlayer board 40 to be folded at and divided into multiple interlayers. The interlayers are substantially equal in size, are substantially equal to the outer panel 20 in size, and are respectively folded at the partition lines 41 to lean toward the outer panel 20 and are flatly stacked on an inner surface of the outer panel 20 to form multiple interlayer 25 used as pockets of the paper wallet. The card slits 401 are arced and formed through the interlayer of the interlayer board 40 that is most distal from the outer panel 20. With reference to FIGS. 5 and 6, the binding strips 30 are affixed between the two topmost interlayers of the flatly folded interlayer board 40 to bind the interlayers on the inner surface of the outer panel 20. After the binding strips 30 are affixed to the interlayer board 40, the foldable cardboard template 10 is folded at the center fold line 21 to be bent toward the inner surface of the outer panel 20 and form a paper wallet. The paper wallet has multiple interlayer compartments. Each interlayer compartment is formed between two of the interlayers 25 of the paper wallet, which exclude the most distal interlayer 25 from the outer panel 20 and are connected with each other at a corresponding partition line, for holding bills. The card slits 401 formed through the interlayer board 40 serve to be inserted in by cards, such as credit card, debit card and the like.

In the present embodiment, the interlayer board 40 has four partition lines 41. The interlayer board 40 is sequentially divided into a first interlayer 42, a second interlayer 43, a third interlayer 44, a fourth interlayer 45 and a fifth interlayer 46 in a direction away from the outer panel 20. Each of the first, second, third, fourth and fifth interlayers 42, 43, 44, 45, 46 has a pocket surface that is on the opposite side to the inner surface of the outer panel 20. The pocket surfaces of the first and the second interlayers 42, 43 and of the third and the fourth interlayers 44, 45 respectively form two interlayer compartments. The longitudinal sides of the first, second, third, fourth and fifth interlayers 42, 43, 44, 45, 46 gradually decrease in length in a direction away from the outer panel 20. The fifth interlayer 46 or the third interlayer 44 is folded at a corresponding partition line 41 so that the pocket surface of the fifth interlayer 46 or the third interlayer 44 leans toward a surface of the fourth interlayer 45 or the second interlayer 43 opposite to the pocket surface of the fourth interlayer 45 or the second interlayer 43. The first interlayer 42 is folded at the connected longitudinal side of the outer panel 20 so that the pocket surface of the first interlayer 42 leans toward the inner surface of the outer panel 20. The fourth interlayer 45 or the second interlayer 43 is folded at a corresponding partition line 41 so that a surface of the fourth interlayer 45 or the second interlayer 43 that is opposite to the pocket surface of the fourth interlayer 45 or the second interlayer 43 leans toward the pocket surface of the third interlayer 44 or the first interlayer 42. The pocket surface of the fifth interlayer 46 faces outwardly after the interlayer board 40 is folded and flatly stacked on the inner surface of the outer panel 20.

After the interlayer board 40 is folded and flatly stacked on the inner surface of the outer panel 20, the binding strips 30 respectively extending from the transverse sides and the longitudinal sides of the outer panel 20 are affixed between the pocket surfaces of the fourth interlayer 45 and the fifth interlayer 46 on the outer panel 20 to securely fix the foldable cardboard template 10 . The pockets 25 are formed between corresponding interlayers. The card slits 401 formed through the fifth interlayer 45 and located on both sides of the center fold line 21 serve for insertion of cards. The folded interlayer board 40 and the outer panel 20 are further folded at the center fold line 21 with the card slits 401 facing each other to form a paper wallet.
